Footage of an Alzheimer's sufferer being repeatedly beaten by a member of staff at a care home will be screened on TV.

The clips claim to show an elderly resident being manhandled by carers at Ash Court Care Centre in Kentish Town, London last year. The footage, which will be aired on the BBC's Panorama, was caught after Maria Worroll's daughter Jane hid a camera in her room.

Jonathan Aquino, 30, was jailed earlier this month for the assault on Mrs Worroll. The Filipino was sentenced to 18 months in jail at Blackfriars Crown Court.

Four of Aquino's female colleagues have since been sacked by the operators of the home, Forest Healthcare, after it reviewed the footage, the documentary says. This is the first time the footage will be aired.

Despite suffering from acute arthritis, Mrs Worroll, 80, was said to be manhandled by her carers and on occasion put to bed at only 5.30pm. On other occasions carers would not greet Mrs Worroll but instead turn on a television to watch while they were in her room, it is claimed.

The documentary also says that one evening's footage, filmed in June 2011, shows a male carer striking Mrs Worroll six times on the face, arms and abdomen. Mrs Worroll was subsequently transferred to a different home.

The Care Quality Commission, the industry watchdog, awarded the care home an "excellent" rating in July 2009, two years before the attacks. A subsequent report, produced four months after the incidents, also failed to mention that charges were pending over the incidents, it is claimed.

A CQC spokesman said: "Abuse of vulnerable people is a criminal matter, and is rightly handled by the police and the courts. CQC has taken action against a number of providers where a current risk to people has been identified. In this case, the risk had been dealt with by the removal of the care staff involved by the home.

"CQC's role was to make sure residents were protected once police and social services had acted to deal with the abuse shown in the hidden camera footage. CQC acted quickly and appropriately in this regard."

The spokesman added: "None of this detracts in any way from the appalling experience Maria Worroll had at this home. CQC welcomes the custodial sentence handed down to Jonathan Aquino."
